RADIATOR.

Specification of Letters Patent.

)Patented Apr.. I8, 1922.

To all lwhom t may concern Beit knownthat I, JOSEPH ALoIs Hno- MADKO, a citizen ofV the United States of America, residing in the borough and county of Queens, city and State of New York, have invented a new and useful Radiator; and I do hereby declare the following to be a full, clear, and exact description of the same.

These improvements relate, especially, to radiators which are principally made up of metallic plates or sheets,y and the objects of the invention are, (l) to provide a form which is cheaply and quickly made, from units each of which is -also cheaply and quickly made; (2) `to`provide a form which may easily and quickly be repaired; to provide. a radiator which gives a maximum cooling area; other objects, as well as the advantages resulting from the invention, will be spoken of hereinafter.

Referring to the accompanying drawings, Fig. 1 is a plan view of a fragment of sheet or plate metal, having frusto-conical projections, enlargements, or cups at opposite faces thereof,'and useful in making the preferred form ofvmy radiator; Fig. 2 is a plan view, showing the water-passages between several sections of a., radiator made according to my invention; Fig. 3 is a front elevation of the construction of Fig. 2, showing the air-passages or compartments; Fig. 4 is a section on the line 1.--4, Fig. 1 through the aforesaid radiator, to show the interconnection, by openings, of the several water-passages; Fig. 5 is a section, on the Y line 5 5, Fig. l through the aforesaid radiator; Fig. 6 is a like detail of a radiator-section where the several vpassages are interconnected by openings; and Fig. 7 is a fragmental front elevation of a radiator according to my invention.

My new radiator may have any desired number of sect-ions. ,lVhen there are a plurality of sections, they shouldbe arranged in In the manufacture of a radiator-section, I preferably employ sheet or plate metal wlnch mayv easily be bent to form the casing or chamber.

Referring to Fig. l, A Aindicates a part of such a plate or sheet, of a materialfor instance, a bronze composition-permitting it to be readily passed Vbetween rollers, or otherwise manipulated, to provide the sheet or yplate with frusto-conical projections,

pockets, or cups at both sides thereof. The

projections or cups, C, from one side of a sheet or plate are shown as' arranged in rows and relativel staggered, while the projections or cups, from the other side of the sheet, are also shown as. arran ed in rows and also relatively staggered. rojections D are shown as being smaller than projections C. Y l .4

The formation -of projections .from and at both sides of the sheet, may be assured, as is well known, merely by passing the sheet between rollers having the surfaces thereof toothed or ot-herwise formed to provide the two series of projections, C and I). Of course, a plate, A may be of any desired length or width, these dimensions depend-l ing upon the size of the radiator-section.

In order te make a radiator-section, a plate or sheet (having projections at both sides) may be folded to have parallel sideplates, B and B', and with projections C inv contact one with another-as shown, enlarged, in Fig. 6. Because the projections C are inside of the radiator-section, I have hereinafter designated those project-ions as inside projections. As a result of the bringing of the side-plates B and B together, the radiator-section has (in the instance illustrated) a long and wide, and a comparatively narrow chamber, the walls of which are strengthened and are spaced apart, at intervals,by contacting or engaged projections C and C. rIhe doubleY bosses, thus formed by the contacting projections C, C are disposed in the path 'of the air currents which arecaused to flow through the sections of the radiaterwhen the car, aeroplane or other vehicle wherein the radiatoris installed is in motion; and since the bosses are spaced apart by their staggered arrangement the air will be free to circulate entirely around the bosses which thus provide a greatly-increased cooling surface and enable a correspondingly-increased cooling action te be obtained.

'ator-section has a flange, a, running along one edge thereof, and also has a flange, a',

along another edge. As shown in the drawings, these flanges are along the front and rear edges of each section. he flanges may be formed by rolling or otherwise treating the sheet ofmetal atthe time that the pro- `jections C and D are formed. The top and bottom of the section are closed, by the parts H and l-l, the former of which is integral with the sides B and B and is produced by the foldi of the blank upon itself, while the part is formed by overlapping the irl-turned bottom edges of said sides.

Any desired number of radiator-sections may be connected, to form a radiator. ln the drawings, ll have shown a group of four sections, arranged side by side, with the flange a of one section in contact with the like flange of the next section, while the Harige a of one sectionis in contact with the like flange of the next section. Contaeting Hanges are secured together, throughout their length of contact. This is preferably done by soldering, which also assuresa water-.tight joint. A group of radiator sections as mentioned, has a plurality of compartments or chambers, as WV, X, Y and Z, and, alternating therewith, compartments or chambers, as y and z. lt will be noted, as shown in Figs. 2, 4 and 5, that the outer (shown as smaller) projections, D, contact, within the compartments g/ and a, and hold the 4wall of one section away 4from the wall of the next section.

As a result of the arrangements described and shown, l produce an exceedingly-strong and simple radiator, of sheet metal, which has a number of compartments or chambers each of which is wide in one direction, so as to have great capacity, and is also narrow in another direction, whereby a maximum number of sections may be included within a minimum space. In practical use, ll preferthat the chambers W, X, Y and Z shall constitute air passages, while the chambers a, y and s shall constitute water passages. Chambers af, y and z are sealed, as before stated, along their top and bottom edges only, and this leaves the water-passages open freel at both ends of the radiator to communicate with the usual headers. Chambers W, X, Y and Z are open at their front and rear, as will be understood, to permit large quantities of air to .sweep straight through thema ll/Vater, while within the water-passages m, y and z, is in the form of thin sheets excepting at the points where vjee-tions being formed wit the projections C are located and, therefore, readily parts with its heat through contact with the walls of adjacent radiatorsections. Those walls are cooled by the air in the chambers W, X, Y and Z. These projections C, as has been stated, extend into the air spaces or chambers and in that way form pockets into which the water flows, the air readily circulating freely around the pockets and readily cooling the water* therein.

lt should be noted, therefore, that the water-contact and radiating space of a waterpassage is increased, to some extent, by the projections C and D, which also increase the surface with which cooling air comes into Contact. j

As shown in Figs. l and 6, the projections or pockets C may have their bottoms pierced, and, when two such projections are brought in contact so as to have the openings of both in register, the material 4at the edge of one opening may be turned or flanged, as at B4 of Fig. 6, over the edge, B10, of the other opening, thus producing Va cross-passage B, from one water-passage to the next. Referring to Fig. 4, it is seen that all of the water-passages may thus be interconnected by cross-passages, at a plurality of points. ln consequence, water,

while passing through the radiator, will flow widthwise and lengthwise of each waterpassage and from passage to passage, and simultaneously in two directions, at right angles to one another, increasing the quantity of water subjected to the cooling action of the air.

ln the present applicationLl have illustrated and described and claimed only a speciic form of my invention, the broader aspects of my invention beingclaimed in my p/Irior granted Patent No. 1,376,882, issued What l claim is l. ln a radiator, a succession of sections arranged side by side, each section .comprising a pair of metallic plates which foi-mathe sides thereof, a plurality of projections extending inwardly from each of said plates and serving to space the adjacent' plates apart, a plurality of projections extending outwardly from each of said plates and serv-l ing to 'space apart adjacent sections, said sections being secured together along their side edges, whereby air passages and water passages are formed side by side and in alternation, and said inwardly extending pron openings, the openings in one plate being in register with the openings in the opposite plate, said openings engaging to form tubular connections from one water-passage to another, to enable water topass through the radiator in independent strearns at right angles to each other.

2. In a radiator, a succession of sections arranged side by side, each section compris' .one direction and comparatively wide in a direction at right angles to said direction and also alternating with air-passages formed between the plates ofI said sections, and the said inwardly extending projections being formed with openings, the openings in one plate fitting into the registering openings in the opposite plate, so as to form tubular connections from one water-passage to another, to enable water to pass through the radiator in independent streams at right angles to each other.
